Can only comment on the modular case, which is 19500 or 30000 for the RYR.
The RYR modular course includes APS MCC and UPRT which is respectively about ~1500 and ~6700.
In the end the total difference amounts roughly 2500 euros then. I am not sure what you'll get 'extra' for the difference in money besides an uniform...
It says train that you'll use the RYR SOP's, I don't know wether this is during the entire training or only during your APS MCC course. In the last case there wouldn't be benefit since you would do this anyway via Sky4U's or VA's APS MCC.
If they've adapted their CPL/ME/IR training to simulate-ish multicrew with RYR SOPs, just like they do during MPL training in the SEP phases, then I could see some benefits.
Anyhow... any kind of MCC included in your training looks like a waste of money at this time. The market probably doesn't pick up anytime soon and as far as I know a recent MCC is more or less required by most carriers when applying for your first job.
